A breaking investigation by EnergyWire appears to connect the dots between shadowy lobbying efforts by shale gas fracking company Range Resources, and the Obama EPA's decision to shut down its high-profile lawsuit against Range for allegedly contaminating groundwater in Weatherford, Texas.

At the center of the scandal sits former Pennsylvania Gov. Ed Rendell, the former Chairman of the Democratic National Committee and the National Governors' Association.

That confidential report, contracted out to hydrogeologist Geoffrey Thyne by the Obama EPA, concluded that methane found in the drinking water of a nearby resident could have originated from Range Resources' nearby shale gas fracking operation.

Range Resources -- which admitted at an industry conference that it utilizes psychological warfare (PSYOPs) tactics on U.S. citizens -- launched an aggressive defense against the EPA's allegations that the company might be responsible for contaminating resident Steve Lipsky's groundwater.

AP explained in its investigation that resident Steve Lipsky, who has a wife and three young children, had "reported his family's drinking water had begun 'bubbling' like champagne" and that his "well... contains so much methane that the... water [is] pouring out of a garden hose [that] can be ignited."

In response, the Obama EPA ordered Range to halt fracking. Range was non-cooperative every step of the way, refusing to comply with the legal dictates of the discovery phase and not complying with the censored water sample study implicating the company with groundwater contamination.

The new twist exposed by EnergyWire's Mike Soraghan is that Ed Rendell, acting "as a spokesman for Range" Resources, "proposed certain terms" to EPA Administrator Lisa Jackson. Exactly what was said remains unclear, but the EPA ultimately dropped its case against Range. More than a thousand pages of emails obtained by EnergyWire "offer behind-the-scenes insights in a case that has come to be seen as a major retreat by the agency amid aggressive industry push-back and support for natural gas drilling by President Obama."

Rendell: Range's Chosen One or Rogue Lobbyist?

The emails obtained by EnergyWire reveal that Rendell intervened directly with Administrator Jackson at some point in 2011, presumably after his term as Pennsylvania's governor came to a close on Jan 18, 2011. An EPA attorney's email indicated that Rendell said he was there "as a spokesman for Range."

"This has been total hell," Lipsky told the AP. "It's been taking a huge toll on my family and on our life."

Determining the truth of what happened with the EPA's failed investigation and lawsuit against Range Resources won't change the Lipskys' predicament, but it would go a long way towards identifying the grasp of the oil industry's tentacles on Washington.
